Assessment Title

Rule Text

OL 8 must not have the "tuned" package installed if not required for operational support.

Description

Discussion Text

"Tuned" is a daemon that uses "udev" to monitor connected devices and statically and dynamically tunes system settings according to a selected profile. Disabling the "tuned" package protects the system against exploitation of any flaws in its implementation.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

if rpm -q tuned >/dev/null 2>&1; then echo "FAIL"; exit 1; fi; echo "PASS"; exit 0

Remediation

Configure OL 8 to disable non-essential capabilities by removing the "tuned" package from the system with the following command: 
 
$ sudo yum remove tuned
